"Open Court Reading©" is a reading program for grades K-6 published by McGraw-Hill Education that is designed to teach decoding, comprehension, inquiry, and writing in a three-part logical progression. Part One of each unit, Preparing to Read, focuses on phonemic awareness, sounds and letters, phonics, fluency, and word knowledge. Part Two, Reading and Responding, emphasizes reading literature for understanding, comprehension, inquiry, and practical reading applications. Part Three, Language Arts, focuses on writing, spelling, grammar, usage, mechanics, and basic computer skills. In 2007, McGraw-Hill Education revised "Open Court Reading©" and changed the name to Imagine It!©. The studies featured in this report evaluate the use of "Open Court Reading©" in grades K-3.
